SIOUX FALLS, S.D. – The Dakota sky glows pale and still this Thursday morning, the air crisp enough to coat lawns and car rooftops in frost. It’s the kind of start that smells like late October—sharp, quiet, and just a bit foretelling of what’s next. By midmorning, sunlight will melt the chill away, but another cold dawn waits on deck for Friday.
According to the National Weather Service in Sioux Falls, widespread frost will blanket much of eastern South Dakota through sunrise. Calm air and clear skies allow rapid cooling near the surface, with low spots in Minnehaha and Lincoln counties dipping near freezing. Gardeners should cover any remaining fall plants, and early commuters may need a few extra minutes to scrape frost from windshields.
Temperatures rebound nicely by midday, climbing near 60°F under full sun. Friday brings another frosty start but a touch more warmth as southerly breezes return. Clouds build late Friday into Saturday, marking a slow transition to milder but less settled weather.
By Sunday night into Monday, a developing system from the Plains could bring the next round of widespread showers—possibly the first in over a week. While no snow is expected yet, this pattern marks a clear shift toward colder, wetter setups typical of late fall. Models hint at near-freezing lows again midweek, keeping the region squarely on “first flake watch” as November nears.
For now, the weekend promises dry fields, bright afternoons, and a few more perfect hours for cleanup before South Dakota’s true winter mood sets in.
